Scholarship / An experience which has given me an opportunity to be a better leader in the future [10]

I believe you should talk more about your professional experience, maybe explore more about how you are now in charge of the career development of your junior staff.

Scholarship / DAAD scholarship is giving tremendous encouragement for young people interested in academic degrees [9]

You should double-check your grammar, first sentence I found this:

With this letter, I am ... in Master's Programs on Communications Engineering in ... and my want desire to request a of scholarship on this purpose.

Take care of the english words you use, my recommendation is that you try to use more synonyms (thesaurus is a great reference for that).

I would focus less on the courses you took during university and more on the extracurricular courses you took.
